In a series RCL circuit the dissipated power drops by a factor of 8.0 when the frequency of the generator is changed from the resonant frequency to a nonresonant frequency. The peak voltage is held constant while this change is made. Determine the power factor of the circuit at the nonresonant frequency. Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise.
A helium-neon laser intended for instructional use operates 7.5 mW. Find out the maximum value of the electric field at a point where the cross sectional area of beam is 10 mm.
A tube is open only at one end. A certain harmonic generted by the tube has a frequency of 470Hz. The next higher harmonic has a frequency of 555Hz. The speed of sound in air is 343m/s.
Then find the force between them as a function of distance h. describe why the sign of the force does (or does not) make sense to you.
